“…The species EV‐A and EV‐B consist of 25 serotypes (Coxsackievirus A2 [CV‐A2] to CV‐A8, CV‐A10, CV‐A12, CV‐A14, CV‐A16, EV‐A71, EV‐A76, EV‐A89 to EV‐A92, EV‐A114, and EV‐A119 to EV‐125) (http://www.picornaviridae.com/ensavirinae/enterovirus/ev-a/ev-a.htm) and 63 serotypes (CV‐B1 to CV‐B6, CV‐A9, Echovirus (E‐1 to E‐7, E‐9, E‐11 to E‐21, E‐24 to E‐27, and E‐29 to E‐33), and EV‐B 69, EV‐B 73 to EV‐B 75, EV‐B 77 to EV‐B 88, EV‐B 93, EV‐B 97 to EV‐B 101, EV‐B 106 to EV‐B 107, and EV‐B 110 to EV‐B 114) (http://www.picornaviridae.com/ensavirinae/enterovirus/ev-b/ev-b.htm), respectively. Among them, EV‐A serotypes as EV‐A71, CV‐A4 to CV‐A6, CV‐A8, CV‐A10, and CV‐A16, and EV‐B serotypes as CV‐Bs and Es can cause HFMD 6,7 . It is established that EV‐As such as EV‐A71, CV‐A16, CV‐A6, and CV‐A10, had been or have become the predominant serotypes 6,8,9 .…”
